| description | The invention discloses a vehicle speed control method and system for endurance mileage tests of electric automobiles. The vehicle speed control method comprises the following steps of: setting vehicle speed control strategies, wherein the vehicle speed control strategies comprise an acceleration segment strategy, a deceleration segment strategy, a zero speed segment strategy, and a constant velocity segment strategy; selecting one or more of the vehicle speed control strategies according to a preset test target; splicing multiple strategies when multiple strategies are selected; acquiring real-time vehicle speed in a test phase; controlling the vehicle speed of the electric vehicle through a PID (proportional Integral Derivative) controller according to the selected vehicle speed controlstrategies and the real-time vehicle speed. According to the vehicle speed control method and system for endurance mileage test of electric automobile, the vehicle speed operating condition is dividedinto four basic operating |
